| Actinomyces strain A01 was isolated from soil of a vegetable field in the suburb of Beijing, China. According to the morphological, cultural, physiological and biochemical characteristics, and 16S rDNA sequence analysis, strain A01 was identified as Streptomyces lydicus. In the antimicrobial spectrum test strain A01 presented a stable and strong inhibitory activity against several plant pathogenic fungi such as Fusarium oxysporum, Botrytis cinerea, Monilinia laxa, etc. However, no antibacterial activity was found. In pot experiments in greenhouse, the development of tomato gray mold was markedly suppressed by treatment with the fermentation broth of the strain A01, and the control efficacy was higher than those of Pyrimethanil and Polyoxin.

| Abstract Benzoic acids preservatives may be converted to benzene in soft drinks. The use of alternative antimicrobial compounds, specifically nisin and natamycin, would reduce benzene formation. Initially, doses of nisin and natamycin were tested against Lactobacillus plantarum lactic bacteria and Zygosaccharomyces bailii yeast. Using 167 UI/mL of nisin and 0.017% w/v of natamycin no microbial growth was reached on lemon-flavored soft drinks. The benzene formation was analyzed in a standard formulation (380 mg/L of sodium benzoate and 180 mg/L of potassium sorbate) and nisin and natamycn formulation (167 UI/mL of nisin and 0.017% w/v of natamycin). The soft drinks were stored without UV exposure at 20 °C and with UV sunlight exposure at 30 °C, for 120... |
